Take a sound pressure level meter (SPL meter). Try to measure the sound pressure p in pascals or in decibels, referred to the threshold of hearing with 20 micropascals.
Decibel scale.
The scale used to define sound intensities is called the decibel scale system. The units used to measure the intensity of sound are referred to as decibels.
The scale 'decibels' is used to measure sound intensities.

- The magnitude of an earthquake can be measured on a scale called Richter scale.- A Richter scale assigns a number each earthquake. This is also known as the Richter magnitude scale.
A magnitude scale. Formerly the Richter magnitude scale was used, but this has now been replaced by the Moment magnitude scale.
A Richter scale used to express the energy released by an earthquake A Beaufort scale is used to derermine the sthrenth of wind.

The scale is the numerical system that is used to define the axis of a graph.

A decibel is a unit of measure of how loud is a sound. Just as inches are used to define length, pounds weight or degrees temperature, decibels define sound levels.
The decibel scale is used to measure the loudness of sound.
Decibels are the scale used for measuring the volume of sounds.
Many scales such as sound and PH are log scales. The scale used to measure earthquakes is also a log scale. Whenever the data has a very wide range, a log scale might help.
Seismologists estimate earthquake intensity based on the reports of witnesses on the level of felt ground movement, on the amount of damage caused by an earthquake and also based on the ground accelerations as measured by seismometers. The scale used to define earthquake intensity in much of the world is the Modified Mercalli scale (before this, a scale known as the Rossi-Forel scale was used). In Europe the Macroseismic scale is in use.
Equally spaced subdivisions. However, a scale need not be divided into equal parts. For example, the logarithmic scale which, among other things, is used to measure the volume of sound - in decibels. The musical scale is approximately logarithmic.
Trigonometry is used to define triangles, but it is also useful in the representation of waves. Sound engineers, obviously, use deal with sound waves. The pitch, volume, and direction of a sound wave are all deeply rooted in trigonometry.
